Caption: [Computer Access: Head Mouse]
Buddy is sitting in a large computer lab with other teens. He is seated
in a power wheelchair with a headrest; his hands are stationary on two
armrests. Buddy is using a head mouse by sipping and puffing on a stick,
as well as moving his head from side to side.
Narrator: “People with good head control, but no use of their
limbs can use a head-controlled pointing system.”
A close-up view shows an infrared detection box on a desk.
Narrator: “This system uses infrared detection and a transmitter
or reflector worn on the user’s head.”
A close-up shows Buddy using the head pointer.
Narrator: “It translates head movements into pointer movement
on the screen.”
Buddy’s back is to the camera and he’s facing his computer
screen while using the headmouse. The computer monitor shows an on-screen
keyboard, with the mouse pointer moving around the screen to activate
various letters.
Narrator: “This can be combined with an on-screen keyboard for
full computer control.”
Buddy is in a computer lab, facing the camera.
Buddy: “Well, The HeadMaster that I use, it just controls the
mouse, the cursor on the keyboard, and the little thing that I blow
into, that’s the button click.”
A close-up shows Buddy blowing into the head mouse wand.
